Introduction of Intel 946GZ + ICH7 Motherboard Series
1-1 Features of motherboard
The Intel 946GZ+ ICH7 chipset motherboard series are based on the latest Intel 946GZ
Express Chipset technology which supports the innovative 65nm and 90nm Dual-Core Intel®
Pentium® D Processor 8 and 9 Series, Intel® Pentium® D Processor, and Intel® Core 2
Duo® (Code Name: Conroe) Processor with Intel® Hyper-Threading Technology. The
motherboard is optimized to deliver innovative features and professional desktop platform
solution with the advantages of the new generation dual core Intel® Core 2 Duo® Processor for
those who demand the best experience of personal computing. Through the high bandwidth of
dual channel DDR2 667/DDR2 533MHz/DDR2 400MHz system memories which are
expandable to 4 GB and the next generation PCI Express interface for the latest graphics cards
from both NVIDIA & ATI.
The Intel 946GZ + ICH7chipset motherboard series for Intel® Core 2 Duo® Processor are
absolutely the cost-effective solution for game enthusiasts and applications, and it also meets
the demanding usage of computing of gaming, multimedia entertainment and business
applications. Moreover, the Intel 946GZ express chipset incorporates Intel Graphics Media
Accelerator 3000 to provide you incredible visual quality, faster graphics performance and
flexible display options without the need for a separate graphics card.
The motherboards implement Intel 946GZ+ ICH7 Express Chipset which supports Front Side
Bus 1333MHz of data transferring and offers with 667MHz memory clock frequency for Dual
channel DDR2 400/DDR2 533/DDR2 667 MHz memory DIMMs to double the performance
of memory access. The motherboard is embedded with ICH7 chipset of providing one parallel
Ultra ATA 100 interface for one IDE drives and four serial ATA2 interface of 3Gb / s data
transfer rate for four serial ATA devices.
The 946GZ + ICH7 motherboard series offer one PCI-Express x16 graphics slot of 4Gbyte/sec
data transfer rate at each relative direction which gets 3.5 times of bandwidth more than AGP
8X and it’s up to a peak concurrent bandwidth of 8Gbyte/sec at full speed to guarantee the
ultimate GPU computing performance. Two 32-bit PCI slots guarantee the rich connectivity
for the I/O of peripherals. The motherboards are designed of tackling the profuse multimedia
requirements nowadays.
The motherboards provide 10 Mbit / 100Mbit Ethernet compatible LAN function by using the
Realtek RTL8102E10/100 PCI-E LAN chip. And the embedded ALC662 chipset fully
compatible with Sound Blaster Prostandards with providing 6-channel Azalia HD CODEC
offers you with the home cinema quality and satisfying software compatibility.
Embedded USB controller as well as capability of expanding to8 of USB2.0 functional ports
delivering 480Mb/s of rich connectivity, these motherboards meet the demands of future USB
peripherals which are also equipped with hardware monitor function on system to monitor
and protect your system and maintain your non-stop business computing.

Some special features---CPU Thermal Throttling/CPU Smart Fan in this motherboard are designed
for power user to use the over-clocking function in more flexible ways. But please be caution that the
over-clocking maybe causes the fails in system reliabilities. This motherboard provides the guaranteed
performance and meets the demands of the next generation computing. But if you insist to gain more
system performance with variety possibilities of the components you choose, please be careful and
make sure to read the detailed descriptions of these value added product features, please get them in
the coming section.
1-1.1 Special Features of Motherboard
CPU Thermal Throttling Technology--- (The CPU Overheat Protection
Technology)
To prevent the increasing heat from damage of CPU or accidental shutdown while at high
workload, the CPU Thermal Throttling Technology will force CPU to enter partially idle
mode from 87.5% to 12.5% according to preset CPU operating temperature in BIOS (from 40
to 90). When the system senses the CPU operating temperature reaching the preset
value, the CPU operating bandwidth will be decreased to the preset idle percentage to cool
down the processor. When at throttling mode the beeper sound can be optionally selected to
indicate it is in working.
CPU Smart Fan---( The Noise Management SystemOnly support 4-pin CPU cooler)
It’s never been a good idea to gain the performance of your system by sacrificing its acoustics.
CPU Smart Fan Noise Management System is the answer to control the noise level needed for
now-a-day’s high performance computing system. The system will automatically increase the
fan speed when CPU operating loading is high, after the CPU is in normal operating condition,
the system will low down the fan speed for the silent operating environment. The system can
provide the much longer life cycle for both CPU and the system fans for game use and
business requirements.

Hardware Installation
2-1 Install LGA 775 Supported Intel Processor
This motherboard provides a 775-pin surface mount, LGA775 Land Grid Array socket,
referred to as in the 775 Pin package utilizes Flip-Chip Land Grid Array (FC-LGA) package
technology.
The CPU that comes with the motherboard should have a cooling FAN attached to prevent
overheating. If this is not the case, then purchase a correct cooling FAN before you turn on
your system.
WARNING! Be sure that there is sufficient air circulation across the processor’s
heatsink and CPU cooling FAN is working correctly, otherwise it may
cause the processor and motherboard overheat and damage, you may install
an auxiliary cooling FAN, if necessary.
To install a CPU, first turn off your system and remove its cover. Locate the LGA775
socket and open it by first pulling the level sideways away from the socket then upward to a
90-degree angle. Insert the CPU with the correct orientation as shown below. The notched
corner should point toward the end of the level. Because the CPU has a corner pin for two
of the four corners, the CPU will only fit in the orientation as shown.

Bank 2, 3 (DIMM2) DDR2 400/ 533 DDR DRAM Module X1 128MB∼2 GB
Total Memory (Max. 4 GB) 2 128MB∼4 GB
Recommend DIMM Module Combination
1. One DIMM Module ----Plug in DIMM1
2. Two DIMM Modules---Plug in DIMM1 and DIMM2 for Dual channel function
For Dual channel Limited!
3. Dual channel function only supports when 2 DIMM Modules plug in either both DIMM1 &
DIMM2
4. DIMM1 & DIMM2 must be the same type, same size, and same frequency for dual channel
function.
Install DDR2 SDRAM modules to your motherboard is not difficult, you can refer to figure
below to see how to install a 240-Pin DDR2 400/DDR2 533/DDR2 667 SDRAM module.

Connectors, Headers & Jumpers Setting
3-1 Connectors
(1) Power Connector (24-pin block) : ATXPWR
ATX Power Supply connector: This is a new defined 24-pins connector that usually
comes with ATX case. The ATX Power Supply allows using soft power on momentary
switch that connect from the front panel switch to 2-pins Power On jumper pole on the
motherboard. When the power switch on the back of the ATX power supply turned on,
the full power will not come into the system board until the front panel switch is
momentarily pressed. Press this switch again will turn off the power to the system
board.
** We recommend that you use an ATX 12V Specification 2.0-compliant power supply
unit (PSU) with a minimum of 350W power rating. This type has 24-pin and 4-pin
power plugs.
** If you intend to use a PSU with 20-pin and 4-pin power plugs, make sure that the 20-pin
power plug can provide at least 15A on +12V and the power supply unit has a minimum
power rating of 350W. The system may become unstable or may not boot up if the
power is inadequate.
(2) ATX 12V Power Connector (4-pin block) : ATX12V
This is a new defined 4-pins connector that usually comes with ATX Power Supply.
The ATX Power Supply which fully supports AM2 processor must including this
connector for support extra 12V voltage to maintain system power consumption.
Without this connector might cause system unstable because the power supply can not
provide sufficient current for system.
